Definitions

  • the invention is concerned with a space-saving 1-stage ejection system for a lightning projectile, in particular for an artillery light projectile.
  • Known luminous projectiles for example for illuminating a battlefield, are based on a 2-stage ejection system. In this case, the timing of the application of the projectiles is controlled by pyrotechnic delay elements.
  • a luminous floor describes the DE 10 2007 057 184 A1 . It is known that, in particular, environmental influences have a great influence on the pyrotechnic charges. This influence additionally leads to a spread in the delay times.

  • light-emitting diodes are used as luminous bodies, which are arranged like an array.
  • the DE 25 18 645 A1 discloses a luminous projectile with a projectile casing and a packing sleeve.

  • the projectile hood another twist brake is arranged, which in turn is formed by swinging wings. These open when they have left the projectile casing and serve to reduce the swirl pot's swirl.
  • Such a structure requires a relatively large space in the floor.
  • the invention is based on the idea of integrating a 1-stage ejection system in the projectile, ie to realize a 1-stage lighting projectile.
  • a 1-stage ejection system in the projectile

  • This idea means that the structure for the luminous floor, which is also cheaper, requires less space in the floor. This creates the use for a larger luminous body, which in turn leads to a longer lighting time.
  • the structural design is distinguished from known projectiles in that the internal structure of the filament is pushed out of the projectile casing by only one ejection charge. There is no 2nd output. The further activation of the sinking parachute takes place by separation of the packaging line from the latter with the aid of the separating device. The timing takes over a delay unit in a known manner.

Description

  • Die Erfindung beschäftigt sich mit einem platzsparenden 1-stufigen Ausstoßsystem für ein Leuchtgeschoss, insbesondere für ein Artillerie-Leucht-Geschoss.
  • Bekannte Leuchtgeschosse, beispielsweise zum Ausleuchten eines Kampffeldes, basieren auf einem 2-stufigen Ausstoßsystem. Dabei wird der zeitliche Ablauf des Ausbringens der Leuchtgeschosse über pyrotechnische Verzögerungselemente gesteuert. Ein derartiges Leuchtgeschoss beschreibt die DE 10 2007 057 184 A1 . Bekannt ist, dass insbesondere Umwelteinflüsse einen großen Einfluss auf die pyrotechnischen Sätze haben. Dieser Einfluss führt zusätzlich zu einer Streuung in den Verzögerungszeiten.
  • Eine Leuchtmunition zur Gefechtsfeldbeleuchtung mit einem Fallschirm offenbart die WO 2009/0468000 A1 . Hierbei werden als Leuchtkörper Leuchtdioden verwendet, die arrayartig angeordnet sind.
  • Die DE 25 18 645 A1 offenbart ein Leuchtgeschoss mit einer Geschosshülle sowie einer Packhülse. In der Packhülse befinden sich ein Vorfallschirm, ein Hauptfallschirm, eine Drallbremse sowie ein Leuchttopf. In der Geschosshaube ist eine weitere Drallbremse angeordnet, die ihrerseits durch ausschwenkbare Flügel gebildet wird. Diese öffnen sich, wenn sie die Geschosshülle verlassen haben und dienen zur Drallreduzierung des Leuchttopfes. Ein derartiger Aufbau benötigt im Geschoss einen relativ großen Bauraum.
  • Hier greift die Erfindung, ausgehend von der DE 25 18 645 A1 , die Aufgabe auf, ein Ausstoßsystem aufzuzeigen, das platzsparender aufgebaut ist.
  • Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen dargestellt.
  • Der Erfindung liegt die Idee zugrunde, ein 1-stufiges Ausstoßsystem in das Geschoss zu integrieren, d.h. ein 1-stufiges Leuchtgeschoss zu realisieren. Mit der Anordnung wird der Drall der drallstabilisierten Leuchtgeschosse über eine entsprechende Drallbremse und zusätzlich nur durch eine Ballute für die/ den Leuchtkörper reduziert. Der Leuchtkörper sinkt dann am Hauptfallschirm mit einer konstanten Geschwindigkeit zu Boden. Diese Idee bewirkt, dass der Aufbau für das Leuchtgeschoss, der auch kostengünstiger wird, weniger Platz im Geschoss benötigt. Das schafft die Nutzung für einen größeren Leuchtkörper, was wiederum zu einer längeren Leuchtdauer führt.
  • Der konstruktive Aufbau zeichnet sich gegenüber bekannten Leuchtgeschossen dadurch aus, dass der Innenaufbau des Leuchtkörpers durch nur eine Austoßladung aus der Geschosshülle geschoben wird. Es erfolgt kein 2. Ausstoß. Die weitere Aktivierung des Sinkfallschirms erfolgt durch Trennung der Verpackungsleine von diesem mit Hilfe der Trenneinrichtung. Die zeitliche Steuerung übernimmt eine Verzögerungseinheit im bekannter Art und Weise.
  • Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt:
    • Fig. 1
    ein in einem Längsschnitt dargestelltes Leuchtgeschoss,
    Fig. 2
    eine vergrößerte Darstellung des Innenaufbaus aus Fig. 1,
    Fig. 3
    eine Darstellung der Vorrichtung zur Seil-Trennung der Verpackungsleine aus Fig. 2.
  • In Fig. 1 ist ein mit 1 gekennzeichnetes Leuchtgeschoss dargestellt. Das Geschoss 1 umfasst einen Geschossboden 2, eine Ballute 3 und einen Fallschirmträger 4. Der Fallschirmträger 4 dient zur Aufnahme eines Sinkfallschirms 5 mit Drallbremse 6. Der Fallschirmträger 4 ist im hinteren Teil einer Geschosshülle 7 des Leuchtgeschosses 1 eingebunden. Im vorderen Teil der Geschosshülle 7 ist wenigstens ein Leuchtkörper 8 integriert, wobei im Ausführungsbeispiel drei Leuchtkörper 8 gestapelt eingebunden sind, die miteinander wirken. Zusätzlich kann eine Packhülse 9 vorgesehen sein, die die Leuchtkörper 8 aufnimmt. Die Geschossspitze ist mit einer Ausstoßladung 10 versehen, die bis an eine Platte 11 bzw. bei Verwendung einer Packhülse 9, bis an den Boden der Packhülse 9, heranreicht. Die Ausstoßladung 10 befindet sich dabei vorzugsweise in einem zentralen Hohlraum. Durch die Ausstoßladung 10 werden der / die Leuchtkörper 8 als auch der Fallschirmträger 4 mit der Drallbremse 6 und dem Sinkfallschirm 5 aus der Geschosshülle 7 herausgedrückt.
  • Eine Verpackungsleine 12 für den Sinkfallschirm 5 führt von der hinteren Platte 16 des Fallschirmträgers 4 (in Flugrichtung des Geschosses 1 gesehen) bis zu den Leuchtkörpern 8. Diese wird für den Gebrauch des Sinkfallschirms 5 getrennt.
  • Eine Trenneinrichtung 13 der Leine 12, hier mit Hilfe eines Seil-Cutters 13', zeigt Fig. 3. Die Trenneinrichtung 13 umfasst einen Schneidstempel 14.
  • Die Funktionsweise ist wie folgt:
    • Mit Zünden der Ausstoßladung 10 wirkt ein Druck auf die Platte 11. Dieser / diese schiebt den gesamten Innenaufbau einschließlich Leuchtkörper 8, Fallschirmträger 4 samt Drallbremse 6, Sinkfallschirm 5 und Ballute 3 aus der Geschosshülle 7 nach hinten heraus. Die weitere Aktivierung des Sinkfallschirms (Hauptfallschirm) 5 erfolgt durch die Trennung der Leine 12 mit Hilfe des Seil-Cutters 13'. Die Auslösung bzw. zeitliche Steuerung des Seil-Cutters 13 kann durch eine Verzögerungseinheit 15 mechanisch / pyrotechnisch erfolgen. Danach wird die Leine 12 durch den Schneidstempel 14 getrennt.
  • Nunmehr kann sich die Ballute 3 entfaltet und übernimmt zusammen mit der Drallbremse 6 die Funktion, den Drall der Leuchtkörper 8 zu reduzieren. Gleichzeitig übernimmt der Sinkfallschirm 5 die Aufgabe, das Absinken der Leuchtkörper 8 zu steuern, so dass die Leuchtkörper 8 am Sinkfallschirm mit einer konstanten Geschwindigkeit zu Boden sinken.
